Digital signing not working in eM Client

eM Client is not properly decrypting signatures, if I send a digitally signed email to an account that is in eM Client (as well as Outlook 2016 for testing). The email shows properly signed in Outlook, but shows an “0 byte unnamed attachment” in eM Client.

Outlook is using EAS while eM Client is using EWS for both accounts.


Is the problem still there or have you managed to resolve it? I have recently tested sending digitally signed emails in version 7 and it worked well.
